I have a bound combobox and depending on the values I get back in the records I want to change the background color of certain rows in the combobox. Is this possible and if so how?
A little more clarification. I'm looking at one of the fields in each row and based on its value I want to change the background color. So I could be changing all of the row, some of the rows, or none of the rows.
Thanks
Use the ItemContainerStyle to set the item background color per-row. You can bind to a property in the row's data context, and use an IValueConverter to get the appropriate brush. Eg, assuming that the items have a property "Y":
<ComboBox>
<ComboBox.Resources>
<local:BoolToBrushConverter x:Key="BoolToBrushConverter" />
</ComboBox.Resources>
<ComboBox.ItemContainerStyle>
<Style TargetType="ComboBoxItem">
<Setter Property="Background"
Value="{Binding Y,Converter={StaticResource BoolToBrushConverter}}" />
</Style>
</ComboBox.ItemContainerStyle>
</ComboBox>
Then the "BoolToBrushConverter" would be something like this:
public class BoolToBrushConverter: IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return (value as bool? == true) ? Brushes.Green : Brushes.Red;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
